Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601732, here are decompositions:

61 + 31601671 = 31601732
103 + 31601629 = 31601732
163 + 31601569 = 31601732
181 + 31601551 = 31601732
193 + 31601539 = 31601732
223 + 31601509 = 31601732
373 + 31601359 = 31601732
541 + 31601191 = 31601732

Showing the first eight; more decompositions exist.
